The E8 series (E8系) is a Japanese Shinkansen high-speed train type on order for Tsubasa services announced on 3 March 2020.

It will progressively replace the E3 series from 2024 onwards, raising the top speed of the service from 275 to 300 kilometers per hour (171 to 186 mph).

The center aisle carpet was designed based on the image of the safflower, represented by the seats, reflecting on the waters of the Mogami River as it flows between them.
